Active matrix electroluminescent device power considerations

Abstract:

An active-matrix electroluminescent (AMEL) design tool has been developed for
the simulation of AMEL display devices. The AMEL design tool is a software package
that simulates AMEL device operation using a lumped parameter circuit model. The
lumped parameter circuit model is developed primarily to address AMEL power
dissipation issues. The AMEL design tool provides a user-friendly approach for
investigating the AMEL display device through the AMEL lumped parameter circuit
model. The AMEL design tool is programmed in C with a standard Microsoft Windows
interface.
Three techniques for power reduction have been identified and investigated:
increasing the high voltage NDMOS transistor breakdown voltage, parasitic capacitance
optimization, and development of a low voltage phosphor.
